## Discrepancy

DURING TAKEOFF CLIMB, THE CREW RECEIVED A LANDING GEAR AIR/GROUND FAULT ON THE EICAS AND THE GEAR HANDLE WOULD NOT MOVE TO A GEAR UP POSITION.  MAINTENANCE INSPECTED THE LANDING GEAR AND FOUND THE LOWER PROXIMITY SWITCHES TO BE OUT OF ADJUSTMENT.  ADJUSTMENTS WERE MADE AND THE LANDING GEAR EXTENSION AND RETRACTION SYSTEM OPERATIONALLY CHECKED GOOD.
